Term
 What is the rule #1 of the Expected number of caculating Probabilites
Definition
 if the events are mutally exclusive, add thier individual probabilities to find the probabilty of any one of them occuring.
Term
 what is rule #2 of the Expected number of caculating probabilites?
Definition
 if the events are independent, multiply their individual probabilities to find the probability will all occur.
Term
 What is the rule #3 of the Expected number of calculating Probabilities?
Definition
 ( for mutually exclusive events) if the probability of event A is " P " and the probability of B is " q" the probability that A will occur exactly " s" times and B will occur exactly "r" times in " n" .
Term
 what is another way of caculating probabilities?
Definition
 mutually exclusive.
Term
 Conditional Probabilities
Definition
 used when we have information about some events , but not all of them.
Term
 What are the 4 steps of Testing Hypotheses?
Definition
 *part of the science method*1. statement of condition or problem2. Form theory and testable hypothesis3. test the hypothesis4. reject or accept ( fail to reject) hypothesis.
Term
 what do you expect to see is what you predict using what ?
Definition
 Punnett Square or algebratic explansion.
Term
 what is the steps for Chi-Square?
Definition
 1. assume the null hypothesis.2. determine the " degrees of freedom"3.caculate the X2 statistic
Term
 Probability of Detection
Definition
 When you run " test crosses" to see if an individual carries a recessive allele, one of two things can happen.1. you observe a recessive phenotype2. you getting the dominant phenotype
Term
 What is the Population Genetics
Definition
 Gene Frequencies: Estimating frequencies
Term
 What is the Hardy-Weinberg Law?
Definition
 (1908) Large randomly mating populations will return to, or reach an equilibrium in 1 generation , providing there are no forces present to change gene frequencies. if the gene frequencies are different between the sexes it will take 2 generations to reach equilibrium.
Term
 What are the three frequencies?
Definition
 1. Migration 2. Mutation3. Selection
Term
 what is mutation?
Definition
 Physical change of 1 allele to an alternate form. 1 time event only happends once.
Term
 what is migration
Definition
 allows us to influence frequencies.
